APPARATUS FOR MAKING BRIQUETS.

Specification of Letters Patent. I

Application filed September 11, 1913. Serial No. 789,234.

To all whom it may concern Be it known that I, SAMUEL B. Gorr, a citizenof the United States, residing at Camden, in the county of Camden andState of New Jersey, have invented certain new and useful Improvementsin Apparatus for Briquets, of which the follow ng is Making aspeclficatlon.

My invention relates. to improvements in apparatusfor making briquets,the object of the invention being to provide improved means for heatingand mixlng the lngredlents for the briquets in an economical manner, andthen discharging the material into molds for drying.

, Afurther object'is to provide improved meansforcrushing thecomposition before its passage into a receptacle in which it is agitatedand'heated with a View to bringing the material, to a liquid state.

A further object is to provide improved 'means for catching and burningthe soot whichwould otherwisepass off through the smoke-pipe.

A further object is to provide improved means for returning to the firebox, the smoke and gases for consumption.

A further object. is to provide improved molds for briquets which willprovide in the briquets, a plurality ofopenings to facilitate theburning thereof.

With these and other-objects in view, the invention consists 1n certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter dcserlbed and pointed out 1n theclalms.

I In'the accompanying drawings: Figure 1.

is a view in vertical section illustrating my improvementsl Fig. 2 is aview tion on theline 2-2 of Fig. 1. Fig. 3 is a view in cross section onthe line 3-3 of plan view of the briquet mold. Fig. '5 is a fragmentaryview in section on the line 5-5 of Fig. 1. Fig. 6 is a fragmentary viewin vertical section illustratinga modification, and Fig. 7 is a view incross section on the line 77 of Fig. 6.

1 represents a cylinder supported upon a casing 2, the latter mounted onan axle 3. The aXle 3 is supported in thehubs 4 of traction wheels 5,and said hubs have keys 6 which lock the wheels to the axle and beremoved Whenever desired, so that the axle may be turnedby a pulley 7 asclearly shown.

in cross seclocated and spaced from the cylinder at its sides as well asat its lower end. The casing 2 is divided by a partition 9 into an uppercompartment forming a fire chamber 10 with a grate 11 therein. gasesfrom thisfire chamber pass upwardly through an opening 12 in the bottomof cyliuderl, thence around the outside of tank 8 into a chimncylil. Thechimney 13 has a damper 14 therein, and between the damper l4 and thecylinder 1, areturn pipe 15 is connected. This pipe 15 communicates witha fan casing 16, the latter having a discharge pipe 17 for directing thesmoke and gases back into the fire box.

A frame 19 secured to cylinder 1, supports 1 a conical grinder or milltary member 21 thereof vertical shaft 20, the conical robeing secured toa 22 which extends into tank 8,

The smoke and and has a thrust hearing at its lower end as shown at 23.A tube 24; is located in the center of tank 8, and houses the shaft 22.Radial arms 25 are fixed to shaft 22 and support agitators or heaters 26which stir the material in the tank. A hopper 27 is supported by theframe 19 and directs the material to be treatedinto the mill 20.

A beveled gear 28 on axle 3 meshes with a beveled pinion 29 on avertical shaft 30.

This shaft 30 is supported in suitable bear-- lugs 31 on cylinder 1, andat its upper ends is connected bybeveled gears 32 with a horizontalshaft This shaft 33 is supported in a bracket 34 fixed to the mill 20,and at its inner end is connected by beveled gears 35 with the shaft 22.

A vertical shaft 36 projects up through a tube 37 in the fire box, andis provided on its upper end in cylinder 1 between the lower end of thecylinder, and the lower end of the tank 8,with a series of radial blades38 for a purpose which will hereinafter appear. A belt39 connects apulley 40 on shaft 30 with a pulley 11 on shaft 36. A belt 42 connects apulley 43 on shaft 36 with a pulley 14. on the fan shaft 45, so that itI will be observed that the turning of the axle 3 will cause rotarymotion to be imparted to the several shafts abovercferred to. The

blades 38 constitute a soot catcher, and they lie in the path of thesmoke and gases from the fire box to the chimney 13. The blades 38 areprovided on their lower faces with angle bars 16 which catch the sootand the consumption of this soot is facilitated by the provision ofmeans for supplying a combustible liquid to the blades. I haveillustrated for this purpose, a tank l? on the outside of cylinder 1which is provided with a pipe 4:8 projecting into the cylinder anddesigned to drip upon the blades.

The blades are perforated as shown at 4.9, so that combustible materialmay find its way through the blades and readily burn the soot. On oneside of the apparatus, and communicating with the lower end of tank 8,is a discharge pipe 50 having a valve 51 therein. This pipe 50 isadapted to dischargethe composition into a series of molds 52 located onthe ground or at some convenient point. These molds 52 have inclinedwalls 53 to allow the briquets when dried to readily fall out of themolds. Each of the molds is provided with pins 54 which leave holes inthe briquets, hence allowing a free draft through the briquets andfacilitating their consumption in the fire box. A faucet 55 is alsoprovided on the tank 8, so that the contents of the tank may be drawnoff-through this faucet whenever desired.

In the modification illustrated in Figs. 6 and 7, the shaft 22 not onlysupports vertical beaters or stirrers 26 which are appreciably shorterthan the beaters 26, but also provides a circular series of horizontallypositioned agitators or heaters 26 These horizontal agitators or beatersnot only cause the material to thoroughly mix, but exert a certainamount of pressure or force back of the material to compel it to fiowout through the outlets. To facilitate this, it will be observed thatthe beaters are at an angle.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
